It was a hot day today so I was wondering what kind of temps I would get. Here's my results:PC specsi7 965 at 3.6ghz with 1.2VcoreGTX 295 dual PCB at 670/1476/1188 with stock voltages

Room temp 82F/28C. Flow rate 1GPM. PC has been on all day.

IdleCPU 40CGPU 1 41CGPU 2 39C

Prime 95 realtemp warm up testCPU 61C

Furmark extreme burn for 2 minutesGPU 1 51CGPU 2 49C

I'm looking at only 3-4C diffrence between a 72F(22C) room using the same tests but my data is outdated and I'll try the same tests again tomorrow when the room is cooler or next week. I'm also going to redo all my i7 clock temp tests when their is another cold day, 3.6-4.13ghz.

Looks like I'm sticking with 3.6ghz at 1.175Vcore(vcore failed back to 1.20 Vcore) until I ever need 3.875ghz. 4ghz isn't safe with my current cooling set up and would require it's own loop. For just 133mhz the temps/power consumption isn't worth it at all compaired to 3.875ghz. Going higher than 4ghz would be a waste of my time as anything above 4.133(1.35Vcore) would need over 1.375Vcore which I'm not going to do.

I'm going to guess your 920 is a D0 because they OC a lot better than the C0 CPU's. I've had my 965 at 4.133@ 1.35Vcore(not 100% tested though) which isn't that far away from your OC. I wouldn't be surprised if you could lower the Vcore on CPU OC.

I am still a little confuse. Really, what is the difference in the i7 design wise up to the extreme additions? What does one gain by going with a higher numbered processor for OC'ing? Are the higher models just there for the people who will not be OC'ing? There has to be something different for the price gap.

The Extreme editions should be easier to OC and should OC higher than normal editions. They also have unlocked multipliers which make setting up ram speeds and OCs much easier also, they also have a higher QPI speed.

I don't see the point of buying a 950/960 over a 920/930 i7, they might OC better or use less power maybe but nothing else. If your going to keep the CPU at stock speeds like a OEM PC then Intel gives you the option to have different speed CPU's.
